PROGRESS IN THE STUDY ON MECHANICAL PROPERTIES OF ANCHORAGE SYSTEM FOR CFRP CABLES

Abstract

Abstract: A review of studies on the mechanical properties of anchorage system for CFRP cables is given in this paper. The emphasis is placed on the recent achievements in this field, in which the experimental and numerical simulation investigations into anchorage system are included. Important developments in this field are discussed. The strength of CFRP tendon can′t be into full play in wedge-type anchorage, and a progressive damage method of predicting the strength of wedge-type anchorage system should be established by using the finite element method. In order to accelerate the engineering application of CFRP tendon, the fatigue characteristics and stress relaxation of anchorage system for CFRP tendons must be further studied. A new structure of CFRP stay cable was proposed, which was advantageous to anchorage and application. In the end, the prospects of some essential areas to be researched on CFRP cables are previewed.

Key words: carbon fiber reinforced polymer tendon, anchorage system, numerical analysis, fatigue characteristics, stay cable design
